Question

我正在尝试设计一个网页，我必须根据所使用的设备类型做出响应。

在尝试这个时，我一直试图让它以不同的方式响应从iPhone到iPad到桌面。

第二个也是最后一个工作得很好。但试图让它在iPhone上调整我想要的方式似乎只是不想这样做。

-webkit-appearance: none; 
}

这一切都在我的网页浏览器中调整得很好但是当我转到iPhone本身时它不会调整大小，直到我将min-width设置为980px。

有人可以提供一些关于出错的建议吗？

您需要将<meta name="viewport" content="width=device-width, initial-scale=1">添加到html代码的<head>部分。
